Rear Damper Replacement

Rear Damper Replacement

NOTE: Except where called out, the illustrations show without active damper system.

Removal

1. Raise and support the vehicle Service and Repair.

2. Remove the rear wheel.

3. With active damper system: Disconnect the damper coil 2P connector (A), and detach the harness clip (B).

NOTE: Be careful not to damage or contaminate the connector.






4. Remove the flange nut (A) while holding the joint pin (C) with a hex wrench (D), and disconnect the stabilizer link (E) from lower arm B.






5. Position a floor jack under lower arm B. Raise the floor jack until the suspension begins to compress.





6. Remove the flange bolt (A) from the bottom of the damper.

7. Remove the flange bolt (C) from the knuckle.

8. Remove the flange bolt (A) from the top of the damper.





9. Lower the floor jack gradually, then remove the damper (B) from the vehicle.

Inspection

1. Compress the damper assembly by hand, and check for smooth operation through a full stroke, both compression and extension. The damper should extend smoothly and constantly when compression is released. If it does not, the gas is leaking and the damper should be replaced.





2. Check for oil leaks, abnormal noises, and binding during these tests.

Installation

1. Position the damper (A) between the body and lower arm B.

NOTE: With active damper system: Position the damper coil 2P connector on the damper facing rearward.





2. Loosely install a new flange bolt (C) to the top of the damper.

3. Raise the floor jack until the hole in lower arm B aligns with the hole in the damper, then loosely install the new flange bolt (A) to the bottom of the damper.





4. Loosely install the new flange bolt (C) to the knuckle.

5. Connect the stabilizer link (A) to lower arm B, and install the new flange nut (C), and tighten the flange nut to the specified torque, while holding the joint pin (D) with the hex wrench (E).





6. Raise the rear suspension with the floor jack to load the suspension with the vehicle's weight.

7. Tighten the flange bolts on the top and bottom of the damper to the specified torque.

8. With active damper system: Connect the damper coil 2P connector (A), and attach the harness clip (B).

NOTE: Be careful not to damage or contaminate the connector.






9. Clean the mating surfaces between the brake disc/drum and the inside of the wheel, then install the rear wheel.

10. With active damper system: Do the memorizing rear suspension full rebound position Programming and Relearning.

11. With active damper system: Start the engine, then make sure there are no active damper system DTCs with the HDS.

12. With active damper system: Do the DAMPER FORCE OPERATION TEST in the FUNCTIONAL TESTS MENU with the HDS, then make sure all four damper units function normally.

13. Check the wheel alignment, and adjust it if necessary Service and Repair.
